E-Bike Motor Power Claim Comparator

Last updated 2026-08-25

A "750W" e-bike and a "1000W peak" e-bike can be the identical motor. Federal law regulates one number; marketing headlines usually lead with the other, bigger one. We fetched four independently owned brands' own current product pages directly to see how each one actually discloses both figures — or doesn't.

The statute doesn't say which number it means — and most brands' own figure doesn't clear it either way. 15 U.S.C. §2085(b), the federal definition of a "low-speed electric bicycle," requires a motor of "less than 750 watts." Five of the six named models below that publish a nominal figure state it as exactly "750W" — read literally, that's not under 750, it's at 750. Only Aventon's own Soltera.2, at 350W nominal, clears the wording without any ambiguity.

One brand's own product URL and its own specs table don't agree with each other. Engwe's EP-2 Pro page is hosted at a URL containing "750w" — but the specs table on that exact page states only "960W peak brushless gear motor," with no nominal figure anywhere on the page to check. Their L20 page does the reverse split: 750W sits in the specs table, and 960W appears only in the page's marketing headline above it.

Every stated figure, unfiltered

This table doesn't depend on what you typed above — every figure here is straight from each brand's own current page.

Brand	Model	Their own nominal	Their own peak	Gap	Clears "less than 750W"?
Aventon	Aventure 3	750 W	1440 W	1.92x	No — exactly at the line, not under it
Aventon	Soltera.2 2.5	350 W	540 W	1.54x	Yes — 350 W is under 750
Lectric	XPress 750	750 W	1310 W	1.75x	No — exactly at the line, not under it
Rad Power Bikes	RadWagon	750 W	not published	—	No — exactly at the line, not under it
Rad Power Bikes	RadRunner	750 W	not published	—	No — exactly at the line, not under it
Engwe	L20	750 W	960 W	1.28x	No — exactly at the line, not under it
Engwe	EP-2 Pro	not published	960 W	—	No nominal figure published to check

What this does not do

It compares seven named models across four independently owned brands, not every e-bike on the market — only models whose own current page states a wattage figure this fetcher could read as plain text.
15 U.S.C. §2085(b) is the federal definition; it doesn't by itself settle what's legal to ride where. States layer their own Class 1/2/3 e-bike rules on top of it, most (not all) using the same 750W nominal figure. This tool checks only the federal statute's own wording, not state or local law, and is not legal advice.
A brand's own "nominal" or "rated" figure is a nameplate convention, not a number measured to sub-watt precision. Reading a stated "750W" as failing to clear "less than 750 watts" is a literal textual point about the label, not a claim that a specific bike has been found non-compliant.
The peak-to-nominal range below (1.28x–1.92x) comes from only four named models that happen to publish both numbers. A fifth brand's motor could easily fall outside it — the peak-only estimate says so explicitly rather than pretending to certainty.
Rad Power's own two pages checked state no peak figure at all; Engwe's own EP-2 Pro page states no nominal figure at all. Both are reported as "not published," never filled in with a guess.

Runs entirely in your browser. Nothing you type is sent anywhere. The jump starter engine coverage comparator found the same "the number that sells the product isn't the one that matters, and it isn't even always disclosed" shape in a different market. The generator noise level comparator found a brand stating its own figure with no shared basis at all, the same way Rad Power discloses one number here and Engwe's EP-2 Pro discloses the other. The drone sub-250g registration weight comparator found the same threshold-written-in-one-unit shape in a different federal rule, with a brand's own optional accessory pushing the identical product over the line. The pressure washer cleaning units comparator found the same "the bigger headline number and the number that actually matters aren't the same one" pattern.
